VACUUM Application led September The present invention relates to vacuumcleaners and especially to vacuum cleaners oit' the portable type andwhich comprise a suction nozzle and a power driven means :for creatina`the suction in the nozzle,

In connection with such cleaners, it is desirable to provide in thesuction nozzle a means which operates on the surface ot the rug,v orcarpet to disturb the nap oit the ruf; or carpet so to loosen theparticles ot dirt and other foreign matter embedded 'therein to enablethe suction to draw out such particles.

The object ot' my invention is to provide an improved construction andarrangement foroperating on the nap ot a rug` or carpet ttor spreadingIthe nap and thereby loosening,` the dirt so as to enable the saine to bepicked up by the suction ot the cleaner, and ttor a consideration otwhat l believe to be novel and my invention attention is directed to thefollowing` speciiicz tion and the claims appended thereto.

ln the drawing, Fig. l is a perspective view with parts broken away, ota vacuum cleaner embodying' my invention; Fig. 2 is a section taken online 2-2, Fig. l; Fig. 3 is a detail perspective view ot aInodiiication; Fig. 4 is a detail perspective view ot a furthermodilication; and Fig. 5 is a detail perspective view ot anothermodification.

In the drawing', l have illustrated my invention as applied to vacuumcleaners ot the electric motor driven type. lt is to be understood,however, that the invention is not limited necessarily to this type otcleaner although it is especially adapted tor use in connection withsuch type.

Referring,- to the drawing, i. indicates the electric motor ol a vacuumcleaner; 2 indi Cates the tan casing; indicates Athe suction fan carriedby the shaft ot motor l; fl indicates the suction nozzle; 5 indicatesthe dust bag; and G" indicates` the handle ot a vacuum cleaner. The typeot cleaner indicated is a known one, and its speciiic construction as sotar desc ibed -forms no part ot' my present invention. It is to be takenas typical o'lf any suitable vacuum cleaner which comprises a suctionnozzle and a suc tion producing means.

According` to my invention, I provide in the suction nozzle ot thevacuum cleaner an agitating),l means tor the nap oft the rug or carpetwhich agitating means moves lon- CLEANER.

gitudinally ot the nozzle, the movement thereof being ettectedpreferably by the mechanism which drives the suction creating;- means.Such agitating nzeans terms in substance a separator for separatinpY orspreading' apart the libres forming` the nap ot the rut,T or carpet andmay take various Vterms and may be ar anged to move in various ways.

in Figs. l and 2 l. have illustrated an enilfiodirnent ot' theinvention. wherein the agitating` means comprises an endless belt `(iupon which projecting elements 7 are fastened by suitable means suoli asrivets. The projecting' elements may take various forms. Preferably,torni them from sheetmetal ot suitable thickness, the metal beingstamped up to provide a central portion tor attachment to the endlessbelt 6 and one or more outwardly projecting arts. rllhe endless belt (3is mounted on suitable guide rollers 8 arranged in the suction opening`ot the cleaner and extends up over a pulley 9 mounted on the end ot' theshaft of motor l. The pulley 9 serves to drive the endless belt, and theguide rollers S serve to cause the belt to travel in a. straight linelongitudinally ot the suction nozzle opening, the guide rollers being.;located in a` straight line just above the plane of the mouth ot thesuction opening.

rllhe rollers 8 are located so that the agitating devices 7 will engagethe rug` or carpet and disturb the nap of the same.

As is known in connection with the operation olli vacuum cleaners, thesuction of the cleaner serves to litt the rug` or carpet up toward thenozzle opening` whereby the opening is sealed. The suction then servesto draw air up through the runA or carpet, the air carryingwith it thedust particles and other jloreign matter in the run or carpet. rllheprojections T, in the moving across the surface oi the rug or carpetscrape the same and serve to separate the fibres ot t-he nap, thusloosening` even deep seated particles and effecting their removal. i

In Fig. 3 is illustrated an arrangement wherein the endless belt is inthe :torni of a chain l0 driven by a spur wheel ll on the end ot themotor shaft. 'lllhe chain is provided with attachment links l2 to whichseparators or agitators 13 are attached by rivets la. This arrangementinox/*idees a. positive drive tor the belt.,

lll() in Fig. 4; is illustrated an arrangement vherein an endless belt15 is formed from rubber and has teeth 16 moulded on its `inner surfacefor engagement with a pinion 17 on the motor shaft. Pinion 17 may beformed of metal. On belt 15 are metal agitators or separators 18 andbetween them are arranged brush members 19.

In Fig. 5 is an arrangement similar 'to that shown in Fig, 4 except thatthe brush members 2O are vulcanized to the endless belt 21.

In accordance With the provisions of the patent statutes, I havedescribed the principle ot' operation of my invention, together with theapparatus which 1 noiv consider to represent the best embodimentthereof, but I desire to have it understood that the apparatus shown isonly illustrative and that the invention may be carried out by othermeans.

lhat Claim as neiv and desire lo lsecure by Letters Patent ot the UnitedSedex is 1. The combination with a vacuum cleaner having' a suctionnozzle and a motor the shal't of which projects into said nozzle, ol anendless carrier in the nozzle which carrier eX- tends over said shaftand is moved lmigi'itudi` nally of the nozzle by said motor, and napdisturbing and separating means carried by said carrier.

2. The combination with a vacuum cleaner havin` .a nozzle, a tan and amotor for driving the tan. et `guide roller meanslocated adjacent to theplane et the mouth ot the nozzle. a belt on .said guide roller means.nap aeitating and separatingr means carried by said belt` and means tordriving` the belt from said motor.

1n Witness whereof, l have hereto set my band this 9th day of September`1917.8.
